Monitoring Podman

eG Enterprise offers a specialized Podman monitoring model that monitors each of the key indicators of the performance of Container Engine - such as the images, pods, containers etc.- and proactively alerts administrators to potential performance bottlenecks, so that administrators can resolve the issues well before end-users complain.

Figure 1 depicts the layer model of an Podman.

Figure 1 : Layer model for Podman

Every layer in the Figure 1 is mapped to various tests, each of which report a wealth of useful information related to the Podman container. Using these metrics, administrators can find quick and accurate answers to the following performance queries:

  • Is the Podman service installed?
  • What is the current status of the Podman service?
  • What is the total count of the Podman images in the server? How many images are used to create the containers?
  • What is the disk space utilization of the images that are mapped to the containers?
  • How many containers are created from each image of the Podman Container Engine? How many containers are actually running and how well the CPU, disk and memory resources are utilized by those containers?
  • How many containers are available in the Podman Container Engine and among them how many containers are currently running? How many containers are added recently and how many are actually removed?
  • What is the uptime of each container?
  • Is the container available over the network?
  • What is the disk space utilization of each container?
  • How well data is transmitted and received from each container?
  • What is the rate of errors that are transmitted through each container?
  • How well the memory is utilized by each container?
  • How well data is read from and written to each container?

Since the Operating System and TCP layers have been elaborately discussed in Monitoring Unix and Windows Servers document, and the tests mapped to the Network Layer have been elaborately discussed in Monitoring Cisco Router document, the sections to come will discuss the other layers in detail.
